The SL20 Articulating Base is a high-precision ball and socket mounting platform that provides free spherical motion over a complete hemisphere. Positional stability is provided via a heavy-duty 3/16" hex socket locking screw (see photo to the right) that can support centralized loads of 50 kg or cantilever loads of 20 N·m (14 ft-lbs). Applications include flexible inspection systems (video or optical microscope), target positioning, and detection systems.
The mounting platform features an array of twenty-five 1/4"-20 (M6 x 1.0) tapped holes on 0.5" (12.5 mm) centers. It can be tilted into arbitrary positions up to 90° with respect to the table surface. The entire ball and socket mechanism can be rotated 360° about the vertical axis. A laser-engraved scale offers 2° graduations, labeled every 10°. The counterbored slots in the base plate provide both imperial and metric compatibility.
